Answer 1

For Swift 4+ put these lines into AppDelegate at didFinishLaunchingWithOptions

let BarButtonItemAppearance = UIBarButtonItem.appearance()

BarButtonItemAppearance.setTitleTextAttributes([NSAttributedStringKey.foregroundColor: UIColor.clear], for: .normal)      
BarButtonItemAppearance.setBackButtonTitlePositionAdjustment(UIOffsetMake(-200, 0), for:UIBarMetrics.default)
